This report is an update of the report on this subject by the same author, published in June 2005 and completed some months before that date. In this update, we have reevaluated the entire subject, introduced some new barrier packaging concepts and products that have appeared in the intervening period, and have updated and polished our market analyses, estimates, and forecasts for 5 additional years into the future.

Despite the fact that much of the basic technology of barrier plastics is the same, we found that progress continues to have been made in the years since the last report on this subject. On the other hand, some relatively "hot" projects and subjects featured in the last report appear to have become less positive. This appears to be especially true with plastic packaging for beer, which was the subject of considerable attention in the last report, with several new technologies unveiled and promoted. Beer is a very difficult product to package because of its high sensitivity to rapid taste degradation from exposure to oxygen. At this time, at least in the United States, barrier polyethylene terephthalate (PET) beer bottles have not shown that they can give the shelf life that glass and aluminum can provide, except for short shelf life beer for sports events and the like.

Others developments prominently featured in the last report, such as increasingly more sophisticated multilayer barrier packaging structures and controlled/modified atmosphere packaging for fresh produce and other fresh foods, continue to grow in importance and usage, and these fields are updated here.
